Answer:
Null hypothesis: The proportion of active Major League Baseball players who have a batting average greater than 0.300 is 0.51 (p equals 0.51).
Alternate hypothesis: The proportion of active Major League Baseball players who have a batting average greater than 0.300 is not 0.51 (p not equals 0.51).
Step-by-step explanation:
A null hypothesis is a statement from a population parameter which is either rejected or accepted (fail to reject) upon testing. It is expressed using the equality sign.
An alternate hypothesis is also a statement from the population parameter which negates the null hypothesis and is accepted if the null hypothesis is rejected. It is expressed using any of the inequality signs.
Answer:
y = 4
Step-by-step explanation:
We have,
5x + 3y = 12 ....(1)
and
-5x + 4y = 16 ....(2)
Adding equation (1) and (2),
0 + 7y = 28
or
7y = 28
Dividing both sides by 7,
y = 4
So, the value of y = 4.
